Labcorp Genetics (formerly Invitae), Labcorp RCV002294934 SCV002596211 pathogenic Intellectual disability, autosomal dominant 5 2023-05-08 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 829 of the SYNGAP1 protein (p.Glu829Lys). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of SYNGAP1-related conditions (Invitae). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 1721258). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt SYNGAP1 protein function. For these reasons, this variant has been classified as Pathogenic.
